Ive enjoyed this a great deal , i always learn something new here. Regarding uv in water treatment plants , consider this. I have a fish pond , probably around 2000 gallons. I also use a iv light on it. Before i started my pond was cludy at certain times. After i installed it it cleared up.
I know this is a science , but i still think uv's help in some incalculable way.
How that can be measured depends on each system.
I do like the recirculate idea to throughly scrub the air , i would just like a way to make it affordable for the homeowner and profitable for the contractor.

you need not clean the coil regularly, more over at the end of the month you will find a reduced electricity bill, because the load is less when the coils are clean, so use UVC lamps, if you need to know how to place them, where to get them in your region ask me, I have been studying uv( ultraviolet) systems for 18 years.

I would be glad to help any one with technical support- about any thing related to UV (ultraviolet).

What product do you have for the typical HVAC system 1-5 tons?
And what are you prices?
You website does not really tell me this info.
Or am I not looking in the right places on your website.
I know you have been posting for many years.

The CU product we manufacture may be used in residential use. Unfortunately we can't post any pricing on this site. In saying that Trane has an exclusive on our product line. We direct all pricing to the nearest Trane rep. Our HVAC in-line products are designed for commercial use. Factory installed has the TCACS logo on it from Trane. If it is a stand alone piece of equipment Trane Global Parts has access to it. Not all locations have acquired stock for their locations but that is coming son. The equipment that is stand alone or field retro fitted has Genesis Air logo on it. If you have any question please fell free to ask online or contact me.

Looking for IAQ help at my home please

I suffer from horrible allergies and living in St Louis, this is the worst it’s been in a long time.

When I installed a new HVAC system in my home 2 ½ years ago, my HVAC guy recommended the Sanuvox R4000 unit and it did seem to work well……….WHEN IT WORKED!!!

I have had 4 units fail, the 1st 2 units were hardwired to my unit’s panel and the 2nd 2 units were “plugged in” to an outlet….without missing a beat, each unit failed to work for any length of time.

My HVAC guys replaced my UVC unit 3 times and then he told me that other customers were having the same problem…..and he was replacing many Sanuvox units all across the city. Installation is not rocket science so that is not the issue here. He finally stopped replacing Sanuvox units due to his out of pocket costs and his distributor finally stopped replacing units due to the # they had to replace. he couldn't afford to keep changing the failed units out labor-wise, even if covered under warranty.

I live in a 1100 SF home, have a 2 ½ ton Goodman HVAC system (14 SEER AC and 93% on the furnace) and would really appreciate your help in finding something that would help clean the air in my home WITHOUT costing me an arm and a leg…..if possible.

Being in the commercial construction business, we have taken salary AND insurance cuts just to keep our jobs!

i have been doing as much on-line research as i can and found this website. My purpose here is NOT to slam Sanuvox....when the unit worked my health WAS better!
My purpose is to find something that helps me at my home, that i can afford.
Any advice or help would be appreciated from the residential IAQ professionals on this site.
thank you!

-A UV light can sterilize a nearby stationary surface. Most residential systems don't need that because they dry out during the off cycle. The baddies can't grow without sustained moisture.
-A UV light can't sterilize the moving air stream in an HVAC system. The baddies get less than a second of exposure as they whiz by the light.
-A UV light can and will require yearly replacement to maintain its output of UV light. The pretty blue hue is obviously not UV. The hue will stay. The UV will not. Your contractor thanks you in advance for the revenue stream.
-A UV light can also break down any plastic and other petroleum based components nearby. Luckily few people ever deal with that because they don't bother changing the lamps on a yearly basis.
-Some UV lights can also put off fancy sounding free radicals that supposedly seek and destroy baddies. They also seek and destroy lung tissue. Think ozone machines - once promoted by some as healthful, now regarded for the pollution makers that they are.

I've seen major mold growth at the inlet of a merv 14 filter,attached to the return inlet of an air handler,that's real close to the coil.
